Receiver's Antenna Installation
The R7008SB has two antennas. In order to maximize signal reception and promote safe modeling
Futaba has adopted a diversity antenna system. This allows the receiver to obtain RF signals on both
antennas and fly problem-free.

R7008SB Receiver
To obtain the best results of the diversity
function, please refer to the following instructions:
1. The two antennas must be kept as straight as
possible. Otherwise it will reduce the effective
range.
2. The two antennas should be placed at 90
degrees to each other.
This is not a critical figure, but the most
important thing is to keep the antennas
away from each other as much as possible.
Larger models can have large metal objects
that can attenuate the RF signal. In this case
the antennas should be placed at both
sides of the model. Then the best RF signal
condition is obtained at any flying attitude.
3. The antennas must be kept away from
conductive materials, such as metal, carbon
and fuel tank by at least a half inch. The
coaxial part of the antennas does not need
to follow these guidelines, but do not bend it
in a tight radius.
4. Keep the antennas away from the motor,
ESC, and other noise sources as much as
possible.
*The two antennas should be placed at 90 degrees to each other.
*The Illustration demonstrates how the antenna should be placed.
*Receiver Vibration and Waterproofing: The receiver contains precision electronic parts. Be sure
to avoid vibration, shock, and temperature extremes. For protection, wrap the receiver in foam
rubber or other vibration-absorbing materials. It is also a good idea to waterproof the receiver
by placing it in a plastic bag and securing the open end of the bag with a rubber band before
wrapping it with foam rubber. If you accidentally get moisture or fuel inside the receiver, you
may experience intermittent operation or a crash. If in doubt, return the receiver to our service
center for service.
